I'm curious. How does starlet handle Wii mode and gamecube mode? Also, are there other modes, such as a difference in access rights between the wii menu, and a running game?
- During Wii mode, the normal Starlet code ("IOS") runs -- during GameCube mode, a compatibility layer called "MIOS" runs. Yes, the system menu has special access rights that go beyond those of a normal game -- for example, it can see the files of all of the games (to allow you to back up save games), and it can initiate firmware updates.

The reason why I bring it up, is because I'm curious what kind of barriers Nintendo has put up to flashing firmware from within a game. (I understand that a flaw has been found in the code dubbed 'BOOT1' which could provide a hole in the chain of trust and open the door for custom firmware which doesn't bother doing security checks. But, can the NAND even be accessed from wii game mode?)
- The raw NAND (encrypted sectors) can be accessed by any game, but that is not useful unless you know the encryption key (which is hard to get). Aside from that, games can access certain parts of the filesystem on the NAND -- specifically, the files that "belong" to that game. Bushing 05:22, 13 February 2008 (PST)
- Some games do firmware updates. 188.8.131.52 01:58, 13 February 2008 (PST)
- No, they don't. Games specify their required IOS version in the TMD -- when the system menu detects that a game requires a version of IOS that you don't already have installed, it checks to see if the disc also contains an update partition. If so, it installs the contents of the update partition before letting you run the game. Games themselves do not have permission to modify firmware. Bushing 05:22, 13 February 2008 (PST)
